[PATCH 3/7] ASoC: codecs: lpass-wsa-macro: drop dead mixer-path gain hack

[Johan Hovold <johan+linaro@xxxxxxxxxx>]

The vendor driver modifies the gain settings behind the back of user
space but some of these hacks never made it upstream except for some
essentially dead code that reads out the (cached) gain setting and
writes it back again on DAPM events.

Drop the incomplete and pointless hack when enabling mixer paths.
